UNIVERSAL BATH'TUB-TRAL'.

Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed March 17, 1919. Serial No. 283,100.

To all whom z'zf may concern.'

Be it known that I, VILLIAM LANGDoN, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Universal Bathtub-Trap; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention has for its object to provide a bath tub trap that may be used for built-in tubs, particularly the built-in porcelain tub and the ordinary tub, and to provide in connection with such a bath tub trap one wherein not only the outlet of the tub will be water sealed but also one wherein the clean-out will be also eiiiciently sealed. 1t also has for its object to provide a bath trap that may be disposed in a variety of positions with reference to the waste pipe of the tub, the waste pipe of the bath tra 3, the cold and hot water pipes of the tulo, as well as with reference to the location of the clean-out cap. It also has for its object to provide a bath trap that is so formed that the waste pipe of the bath trap may be placed near the top edge of the supporting rafter, and just below the ooring to permit the proper fall of the pipe to cause flow of the water from the bath trap and the tub. The invention also has for its object to provide a bath-trap that will permit the location of its clean-out and its connection with the waste pipe of the bath tub and the overflow pipe of the bath tub as well as the hot and cold water pipes of the bath tub within the paneled space between the sides of the wall usually found in connection with built-in porcelain tubs. 1t also has for its object to provide a trap that may be placed close to the fixtures, that is, without the use of intervening nipples and elbows, and one wherein the waste will drop directly into the trap.

Other objects and advantages of the invention will appear in the following description and upon examination of the drawings.

The invention may be contained in traps of diierent forms. I have selected a bath 'trap for purposes of illustration and shall describe the same hereinafter. The bath trap selected is illustrated in tne accompanying drawings.

Figure l of the drawings illustrates a sectional view of the panel and a side view of a built-in porcelain tub and of the universal trap connected therewith. Fig. 2 is a top view of the trap and tub, the floor of the paneled space vhaving been removed. Fig. 3 is a perspective View of the trap. Fig. 4 is an end view of the ordinary bath tub and a side view of the trap. Fig. 5 shows a sectional view taken on the line 5, 5 indicated in Fig. 4 and an end view of the 1, in the figures, is the built-in porcelain tub. 1t is located on the ioor 2 and is set into the wall 3 which is provided with the paneled space 4 located between the studding of theV wall. The paneled space is closed by the door 5. Within the paneled space is located the overflow pipe 6 in which is located the outlet pipe 7 for the overflow which also forms the puppet-valve that controls the waste fromthe tulo of the form well known inthe art. 'The overflow pipe is connected by a T 8 to the waste pipe 9 of the tub. The outlet of the T is controlled by the puppet-valve located on the end of the pipe 7 and at the lower end of the T S. The tub l is connected to the waste 9.

The universal trap 10 is provided with three arms 11,12 and 13 which radiate from the center of the trap and may be formed in the shape of a Y. rlhe ends of the radiating portions are turned upward and are threaded to receive the three connections, namely, one for the bath tub waste, the other for the clean-out, and the other, the waste pipe. Any one of the connections maybe made with any of the ends of the radiating arms or portions ofthe bath trap and yet the bath trap will afford a water seal for any one and all of the connections because of the length of the arms of the bath trap and because the axes of the arms are located in Substantiallythe same plane. Inasinuch `as any one of the connections may be made with any one of the arms the bath trap may be located not only in any three positions withreference to the three connections but also the bath trap may be locatedy in any position about any one of the fixed points of connection, that is, it may be rotated or located in any position about the overflow pipe which is generally located lit either' in line with the center of the end of the bath tub or in linewith the center of Y the side of the bath tub and the center of the tub. This permits the location of the clean-out in any desired position and is ad- 'Y vantageous in -that it permits the location of the clean-out cap within the panel usually provided in built-in tubs and atfthe same time permits ready connection with the outlet of the bath trap, that is, the waste pipe of `the bath tra-p at any point so that in case of leakage or freezing repair may be easily made. The arms radiating from a center and their a'X-es being located in a horizontal plane and being of considera-ble length, and

the upturnedends being short, plenty ofl space is aorded between the ceiling and the floor by the joists without crowding of the` pipes and their connections andyet at the same time places the outlet orfwaste or sewer pipe vat a point near the licor at the end where it is connected with the bath trap and thus permits an extending fall of the waste water which is particularly of advantagewhen the waste pipe is to be connected Vwith a drain pipel located across the bath room, a condition which invariably exists in bath room plumbing'. If the connection with the bath tub throughl the T 8, the waste pipe 9 and the overiio-w pipe 6 is made with the arm 13, the clean-out pipe 14 may be connected with the arm 12. The clean-out piper14 is closed with a cap 15. This locates `the cap 15 within the area of the ioo-r of the paneledspace 4 and is readily accessible'y for cleaning the trap.V If thev clean-out pipeV 14 is connected with the arm 12, the waste or sewer pipe 16 may be connected with the arm` 11. This may be used when the pipe 16 is to be 'connected with the drain in a line of'direction that passes beneath the bath tub. However, the trap 12 may be lswung around the T 8' and still locate the clean-out cap 15 within the area of the oor of the paneled space 4 and locate the arm 1v1, with which the pipe 16 is connected, at any position and so Kas to place the pipe 16 in a line of direction which extends away from thebath tub,or the T 8 may beconnectedwith the arm 12 as shown in the dotted position indicated. in Fig. 2 and the Copies of this patent may be obtained for clean-out located on the other side the overflow pipe 6. This gives a wide latitude of selection of positions for the bath Vtrap notwithstanding the limitation of the risers, such as the hotand Coldwater pipes, the position ofthe goists, etc., in orderl that a proper sealing connection may be made with the three pipes leading to' and rfrom the trap.- v l Y ln this ordinary tub it is found desirable t0 locate the clean-out. cap 15 directly opposite the overflow pipe 17. At any rate such an arrangement issomewhat symmetrical andgives a better appearance tothe plumbing. In the arrangement Vshown in Figs.,4 and 5, the waste pipe 18 of the crdinary tub 19 is connected through a T 20 to the arm 12 of the bath trap while the clean-out pipe` 14 is connected` tothe arms 13 of the trap. The clean-.out pipe 14, however, may be connected with the arm 11 and turned in any position and the waste pipe 16 connected with the arm 13. The

connection may thus be varied as may be desired, or as may be necessary, because of location of the jo-ists and of the hot and cold water pipes th-a-trlead to the bathtub, and yet notwithstanding,any such connections that may be made, thewater seal of the outlets and the inlets. `from the bath trap Will be through the arms of the bath trap which are of suflicien-t length to warrant a perfect water seal, sorthat notwithstanding any connections that may be made, the sewerV gas will not be permitted `to enter the room either through the bath tub wastel or through the clean-out pipe.
